IMediaObject::GetInputStreamInfo (Windows CE 5.0)

Send Feedback

This method retrieves information about an input stream, such as any restrictions on the number of samples per buffer, and whether the stream performs a lookahead on the input data. This information never changes.

HRESULT GetInputStreamInfo(DWORDdwInputStreamIndex,DWORD* pdwFlags);

Parameters

  • dwInputStreamIndex
    Zero-based index of an input stream on the DMO.
  • pdwFlags
    [out] Pointer to a variable that receives a bitwise combination of zero or more DMO_INPUT_STREAM_INFO_FLAGS flags.

Return Values

Returns an HRESULT value. Possible values include the following.

Value Description
S_OK Success
DMO_E_INVALIDSTREAMINDEX Invalid stream index
E_POINTER NULL pointer argument

Remarks

The DMO_INPUT_STREAMF_HOLDS_BUFFERS flag indicates that the DMO performs a lookahead on the incoming data.

The application must be sure to allocate sufficient buffers for the DMO to process the input. Call the IMediaObject::GetInputSizeInfo method to determine the buffer requirements.

Requirements

OS Versions: Windows CE .NET 4.1 and later.
Header: Dmo.h.
Link Library: Dmoguid.lib.
